To all whom it may concern:

Be it known that I, JULIUS A. THIEMANN, a citizen of the United States, residing at lVashin 'ton, in the District of Columbia, have invented new and useful Improvements in Package-Tie Fasteners, of which the following is a specification.

This invention relates to package tie fasteners and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide a tie fastener of simple and durable struc ture adapted to be applied to boxes or other containers and which will firmly and effec 'tually grasp the binding cord or string whereby the cover of the container or receptacle will besecurely held in place wlthout tying the cord or string.

A further object of the invention is to provide a device of the character stated which may be applied at opposite sides of the box or receptacle whereby the binding cord or string may be extended across the cover or a side of the box and the intermediate portion thereof may be used as handle for carrying the box.

A still further object of the invention is to provide in a device of the character stated a disk or spring or flexible material adapted to coast with a head portion and shank of the device in gripping or grasping the cord or string and which also serves as a resilient means for causing the pointed end portions which are provided upon the shank to firmly engage the inner surface of the side of the box when the shank is passed through the same and the said pointed portions are spread. Hence the said disk performs the dual function of serving as means forgripping the string and as means for securely aiiixing the fastener in position upon the box or receptacle. That the said disk may have maximum spring or resiliency it is made of thin sheet spring metal and the disk is provided with concentrically arranged corrugations which tend to increase the re silienoy of the disk.

In the accompanying drawing:

Figure 1 is a side edge elevational view of the package tie fastener.

Figure 2 is a transverse sectional view of the tie fastener showing the same applied to a portion of a box or container.

Figure 3 is a perspective view of a resilient disk used in the tie fastener structure.

As illustrated in the accompanying drawing the package tie fastener comprises a tu bular shank 1 which is incised longitudinally at one end portion forming pointed end portions 2 which are adapted to be spread radially when the shank is passed through the side of a box or container. A head member 3 is mounted upon one end portion of the shank 1 and the said head is of relatively rigid or inflexible material.

A disk 4; is mounted upon the shank 1 at a point between the head 3 and the pointed end portion 2 of the shank. The disk is provided with a central perforation 5 which receives the shank. The disk 4: is of very thin spring steel or metal and is generally concavo-convex in configuration and is provided with aseries of concentrically arranged corrugations 6. The intermediate or central portion of the disk t bears against the inner or under side of the head 3 and the peripheral portion of the disk lies over or opposite the points of the portions 2 When the same are spread as shown in Figure 2 of the drawing.

When the device is applied the points of the shank are passed through the side, as indicated at 7 in Figure 2, of the box or container and the pointed end portions 2 of the shank 1 are spread radially and the disk t is slightly compressed or distorted as indicated in Figure 2 whereby the side of the box is firmly held between the peripheral portion of the disk and the pointed end portions of the shank.

Therefore when a binding string or cord is wound once or several times around the shank 1 and between the head 3 and the central portion of the disk 4 the said string or cord is gripped or grasped between the head and the disk and is held without tying. The corrugations 6 permit the disk 4 to spring or flex readily so that the said disk may readily perform the dual function hereinbefore referred to.

Having described the invention what is claimed is signature.
